The organization of Micro Four Thirds manufacturers has a nifty website. There you will find a complete list of all the Micro Four Thirds-compatible lenses as of Feb/2019.
The list is free of charge and represents offerings from nearly two dozen companies.
It shows just how far the M43 standard has come in a few short years. No matter what kind of photography you do, changes are, there’s a Micro Four Thirds lens that will meet your needs.
